[pkg-apparmor] Bug#845232: Error on Jessie installation

[Jean-Michel Vourgère]

Package: apparmor
Version: 2.9.0-3
Severity: normal

When installing AppArmor on Jessie, on gets:

Preconfiguring packages ...

I expected not to have warning about "Insufficient privileges", and I expected
action "start" to succeed, obviously. ^^
